The EVE INR21700/40PL stands out with its proprietary full-tab (full pole tab) technology, replacing traditional single/multi-tab design with a full-surface conductive layer on the current collector, plus copper lamination and penetration welding. This reduces internal resistance by ~60% (typical 3.2mΩ), cuts heat generation by ~60%, and boosts power by 100% vs. standard 21700 cells. Specs include 3.6V/4000mAh, 8A max charge, 70A max discharge, 90A peak discharge, and 223Wh/kg energy density. Perfect for high-drain devices: cordless power tools, vacuum cleaners, e-scooters, and outdoor power stations. Grade A, brand new, with strict quality control for consistent batch performance.
